ZFS-USERSPACE(8) System Manager's Manual ZFS-USERSPACE(8)

zfs-userspaceDisplays space consumed by, and quotas on, each user or group in the specified filesystem or snapshot.

zfs userspace [-Hinp] [-o field[,field]...] [-s field]... [-S field]... [-t type[,type]...] filesystem|snapshot|path

zfs groupspace [-Hinp] [-o field[,field]...] [-s field]... [-S field]... [-t type[,type]...] filesystem|snapshot|path

zfs projectspace [-Hp] [-o field[,field]...] [-s field]... [-S field]... filesystem|snapshot|path

zfs userspace [-Hinp] [-o field[,field]...] [-s field]... [-S field]... [-t type[,type]...] filesystem|snapshot|path
Displays space consumed by, and quotas on, each user in the specified filesystem, snapshot, or path. If a path is given, the filesystem that contains that path will be used. This corresponds to the user, user, and user properties.
Do not print headers, use tab-delimited output.
field
Sort by this field in reverse order. See -s.
Translate SID to POSIX ID. The POSIX ID may be ephemeral if no mapping exists. Normal POSIX interfaces (for example, stat(2), ls -l) perform this translation, so the -i option allows the output from zfs userspace to be compared directly with those utilities. However, -i may lead to confusion if some files were created by an SMB user before a SMB-to-POSIX name mapping was established. In such a case, some files will be owned by the SMB entity and some by the POSIX entity. However, the -i option will report that the POSIX entity has the total usage and quota for both.
Print numeric ID instead of user/group name.
field[,field]...
Display only the specified fields from the following set: type, name, , . The default is to display all fields.
Use exact (parsable) numeric output.
field
Sort output by this field. The -s and -S flags may be specified multiple times to sort first by one field, then by another. The default is -s type -s name.
type[,type]...
Print only the specified types from the following set: , posixuser, smbuser, posixgroup, smbgroup. The default is -t posixuser,smbuser. The default can be changed to include group types.
zfs groupspace [-Hinp] [-o field[,field]...] [-s field]... [-S field]... [-t type[,type]...] filesystem|snapshot
Displays space consumed by, and quotas on, each group in the specified filesystem or snapshot. This subcommand is identical to userspace, except that the default types to display are -t posixgroup,smbgroup.
zfs projectspace [-Hp] [-o field[,field]...] [-s field]... [-S field]... filesystem|snapshot|path
Displays space consumed by, and quotas on, each project in the specified filesystem or snapshot. This subcommand is identical to userspace, except that the project identifier is numeral, not name. So need neither the option -i for SID to POSIX ID nor -n for numeric ID, nor -t for types.
